Problem in Payroll Posting

Dear Expert,

Our client decide to paid increment to the employees in July 2015. So we enter new salary in master data effect from April 2015 and run payroll with arrears calculation. Payroll calculation done correctly, but when we try to post the amount in Finance SAP shows some error.

Here posting log showing posting driver running for 3 months only, July result not showing in the log.

Posting log showing current amount and previous amount but arrears component not coming in Posting Log.

We maintain Posting characteristic for Arrears wage types. Please help it's very urgent.

Thanks
